A leu402pro Mutation of the Non-hla Gene il18rap in Aggressive Neonatal Type 1 Diabetes Mellitus

Dirlewanger Mirjam , Blouin Jean-Louis , Bevillard Jeremy , Santoni Federico , Schwitzgebel Valerie

Background: Neonatal diabetes mellitus is defined by severe hyperglycemia appearing before 6 months of age. It occurs in about one in 200 000 live births and most cases are known to be of monogenic origin. Classical autoimmune type 1 diabetes mellitus (DM) is exceptional in this age group.Objective and hypotheses: Recently non-HLA type 1 DM susceptibility genes, such as IL18RAP, influencing the rate of progression to diabetes among children with...

Late Presenting Girls with Turner Syndrome can Achieve a Normal Final Height

Sakka Sophia , Shaw Nick , Kirk Jeremy

Background: The diagnosis of turner syndrome (TS) must be included in the differential diagnosis of all girls with short stature. Despite overall earlier diagnosis and treatment there still remain patients with TS who present late with delayed puberty. Although growth hormone (GH) is known to increase final height (FH) in girls with TS, little evidence exists on treatment in late-presenting girls.Objective and hypotheses: To assess the effect of late GH ...

Capillary TSH Cut-off Levels for Congenital Hypothyroidism Screening: Evidence Against Adopting the UK Threshold of 10 mIU/l

Jones Jeremy , Shaikh Guftar , Mason Avril

Background: The recommended capillary TSH cut-off level for neonatal screening for congenital hypothyroidism (CH) in the UK is 10 mIU/l. However several of the regional screening laboratories have adopted lower cut-off limits in order to increase detection sensitivity. There is now pressure to standardise the UK screening programme with universal adoption of the recommended cut-off. Scotland has been using a cut-off of 8 mIU/l since the adoption of AutoDELFIA TSH screening met...

Phenotypic and Genotypic Variability of Patients with 5-α Reductase Type 2 Deficiency

Hu Kun , Krone Nils , Kirk Jeremy

Background: Steroid 5-α reductase type 2 (SRD5A2) deficiency is an rare inherited disorder resulting from mutations in the SRD5A2 gene, causing 46,XY DSD (Disorder of Sex Development). The mutated SRD5A2 enzyme can no longer convert testosterone to dihydrotestosterone, which is needed for virilisation of external genitalia.Objective and hypotheses: To describe the phenotype, investigations and management of SRD5A2 deficiency.<p class="a...

A Young Type 1 Diabetic with Acute Hemichorea: Rare Central Nervous System Complications

Sng Andrew , Lin Jeremy , Zain Amanda , Lim Yvonne

A 20-year old lady with poorly controlled type 1 diabetes mellitus diagnosed since 9 years old, comorbidities of hyperlipidemia and steatohepatitis as well as a history of smoking, presented with an acute 2-day history of involuntary, writhing movements of her left upper and lower limbs. Physical examination confirmed left mild hemiparesis with hemichorea-athetosis. Emergent MRI brain demonstrated abnormal signal in the right caudate nucleus and lentiform nucleus (low T2W/FLAI...

Transient TSH Elevation in Infants Referred on Newborn Screening – Features, Prevalence and Trends

Ouarezki Yasmine , Jones Jeremy , Fitch Moira , Shaikh Guftar , Donaldson Malcolm

Background: Up to 20% of infants referred on newborn congenital hypothyroidism (CH) screening are subsequently shown to have transient TSH elevation rather than permanent CH. Correct identification of such cases is important to avoid prolonged treatment with thyroxine and unnecessary clinic attendance.Objective: To determine the prevalence, trends and profile of infants with transient TSH elevation referred between August 1979 and December 2015 by the Sc...

Idiopathic Multiple Pituitary Hormone Deficiency (IMPHD): Radiological and Perinatal Factors

Ginige Nimasari , Kirk Jeremy M W , MacPherson Lesley K R

Background: Most cases of multiple pituitary hormone deficiency (MPHD) are acquired and genetic aetiology is rare in the UK. We have investigated whether environmental factors are implicated in ‘idiopathic’ MPHD (IMPHD).Objective and hypotheses: In IMPHD to determine perinatal risk factors and radiological features; to identify the regional epidemiology.Method: Systematic analysis of paediatric IMPHD cases in the UK West ...

Mosaic PHEX variants are important causes of X-linked hypophosphataemic rickets.

Prentice Philippa , Owens Martina , Brain Caroline , Allgrove Jeremy , Gevers Evelien ,

Introduction: X-linked hypophosphataemic rickets (XLH), due to mutations in the PHEX (Phosphate-regulating Endopeptidase homolog; X-linked) gene, causes reduced bone and dentin mineralisation and decreased renal phosphate reabsorption. Mosaic PHEX mutations are reported only in a few case reports.We report three male cases, with mosaic pathogenic PHEX variants, showing importance of considering this in the diagnosis of XLH.Case 1 pre...

Idiopathic Hypoparathyroidism in a 10 Year-Old Girl with Concomitant Epilepsy, Long Q-T Syndrome (LQTS), Pericarditis and Pneumonia

Borysewicz-Sańczyk Hanna , Sawicka Beata , Kiryluk Barbara , Szumowski Piotr , Allgrove Dr. Jeremy , Bossowski Artur

Introduction: PTH is one of the principal regulatory hormones for calcium and phosphate homeostasis. Hypoparathyroidism, caused by reduced parathyroid hormone (PTH) concentration is characterised by hypocalcemia and hyperphosphataemia. Hypoparathyroidism in children can occur either as part of a genetic syndrome, autoimmune disorder, be acquired secondarily to thyroidectomy or some destructive process of the glands. If the reason for decreased PTH concentration is unknown, it ...

Pitfalls in the Diagnosis of An Infant with 46,XX DSD with Congenital Adrenal Hyperplasia due to Cytochrome P450 Oxidoreductase Deficiency – the Value of Simultaneous Genetic Analysis to the Diagnosis in DSD

Idkowiak Jan , Mohamed Zainaba , Allen Stephanie , Chandran Harish , McCarthy Liam , Kirk Jeremy , Cole Trevor , Krone Nils

Introduction: Congenital adrenal hyperplasia (CAH) is the underlying diagnosis in most newborns presenting with 46,XX disorders of sex development (DSD). Cytochrome P450 oxidoreductase deficiency (PORD) is a rare form of CAH caused by inactivating mutations in the POR gene. POR is a crucial electron donor to all microsomal type 2 P450 cytochromes (CYPs), including 21-hydroxylase (CYP21A2) and 17alpha-hydroxylase (CYP17A1). The hallmark feature of PORD is combined sex-steroid a...
